Introduction: The aim of thestudy was to determine atherosclerotic risk factors and angiographic view in veterans and or retired militants underwent CABG in comparison with civilians in Iran. No document were found addressing prevalence of CAD risk factors in Veterans and or Retired (V&R) in Iran. Material and Methods: 61 V&R and 61 civilian aged 39-88 candidates for CABG operation were selected. The investigation conforms with the principles outlined in the declaration of Helsinki. Data were collected via interview and reviewing hospitality profile. Demographic characteristics and Minor& major risk factors were assessed and the Data were analyzed using SPSS ver. 11.5 software. Statistical tests used were T.test, Chi-square and Fisher’s Exact Test. Results: Mean age was 57.36±10.09 and 61.72±9.61 years for the V&R and civilian respectively. Pre-operation Ejection Fraction (EF) was 47.4±8.9 and 46.7±11.45 for the V&R and civilian respectively. A significant differentiation was found between the mean age of CABG in the two groups (P<0.01). No significant differences were found in risk factors of CAD comparing the two groups. The main risk factors of CAD led to CABG were hypercholesterolemia, BMI (≥25), low physical activity and hypertension. Conclusions: The results support some prior studies in the field both in Iran and other countries. Unique characteristics of the military and stressful situations during active-duty time may be important factors results in CAD morbidity after leaving military organizations. Veterans and re-tired military personnel should consider a group need to CAD screening and supportive measurements after departure. (Clin Exp Med Lett 2007; 48(3):153-156)
